About DriftCSS

DriftCSS is an open-source build-time CSS extractor. You write ordinary semantic CSS and static className / cn() / clsx() in JSX. At build time the tool expands shorthands, hashes each declaration into an atom, dedupes those atoms across components, and rewrites the markup. There is no runtime style engine and it is not a utility-class framework.

The project is in alpha (0.1). The supported path is Vite + React + TypeScript. Stay on the npm alpha tag until 1.0; the latest tag is not published. Next.js and Vue are not this release.

Source lives at github.com/MarioCadenas/driftcss. Updates and conversation: @Drift_CSS on X. The public documentation site is driftcss.com. Packages: @driftcss/vite (plugin you install), @driftcss/core (native extractor), driftcss (CLI), and eslint-plugin-driftcss.

DriftCSS is released under the MIT License. It is a personal open-source project, not a registered company and not a hosted CSS service. There is no paid plan on this origin.

Maintainer: Mario Cadenas (MarioCadenas on GitHub). Questions, bugs, and proposals go through GitHub issues — see Contact.

This about page exists so humans and agents can tell what the software is, where the source is, and that the public site is documentation for that software rather than a SaaS product.
